Implementing it in the overrides as PyGObject won't be able to properly
convert python values to GValues in some cases. Using
g_object_set_property works as some logic is implemented inside
PyGObject for that particular case. This is a "regression" due
to https://bugzilla.gnome.org/review?bug=769789&attachment=348766 were
we end up with an OverflowError while setting G_TYPE_UINT children
properties.
In the (now tested) scenario where we have a transition on the right
side of a clip we are splitting, auto transitions can't be created
because we resize the clip after adding the new one, meaning that
there are 3 elements in the "transition zone", we need to force
auto transition creation after the splitting.
Fixes https://gitlab.gnome.org/GNOME/pitivi/issues/2142
In some cases when rippling clip we could get the algo lost because
a transition existed between two clips (for example at the end of c1
and at the begining of c2) but while rippling it would have required
a transition at the end of c2 and beginning of c1, and we were properly
not destroying the old one (as the two clips were in the moving context)
but we were still creating the other transition in the end...
